Concave Collider Lite

ConcaveColliderLite is a lightweight Unity editor tool for building compound convex MeshColliders from a concave mesh.

Instead of using a single large convex hull (often inaccurate) or a non-convex MeshCollider (best for static geometry), ConcaveColliderLite decomposes your mesh into multiple smaller hull meshes, stores them inside a ScriptableObject asset, and then spawns them as child MeshCollider parts. This approach keeps your object compatible with dynamic Rigidbody physics while providing much better collision fidelity than one hull.

Typical use cases:

• Vehicles / car bodies / shells
• Complex props with holes or curved shapes
• Interactive debris and pickups
• Skinned meshes (snapshot bake from SkinnedMeshRenderer)

Core workflow:

1. Select an object with MeshFilter (or SkinnedMeshRenderer).
2. Add ConcaveCollider component.
3. Bake hull meshes into a ConcaveColliderAsset.
4. Press Apply to spawn compound colliders (CC_Part_* children).
5. Optional: enable Generate On Awake to apply automatically in Play Mode.

Notes:

• Apply creates colliders only (physics). To visualize, use Unity Physics Debugger and enable Colliders.
• For best results, bake from the lowest LOD mesh to reduce convex cooking warnings and improve performance.
